VHDX can align to 512, 512e and 4096 byte disks Dynamic/Differencing VHDXs grow 10x faster than VHD 40% faster 64k writes to a fully expanded VHDX VHDX online resize: Resize-VHD -path C:\temp\test.vhdx -ToMinimumSize

Shared VHDX (vSAS) for Fixed and Dynamic disks Storage QoS per VHD Soft minimums, hard maximums CSV re-balancing RDMA flooding 8KB IOps increased from: 300,000 IOps per interface to 450,000
